Queue Length
Outgoing calls can wait in a queue, in the order in which they were made, when all trunks in a
trunk group are busy. If you enter 0, callers receive a busy signal when no trunks are available.
If you enter a higher number, a caller hears confirmation tone when no trunk is available for the
outgoing call. The caller can then hang up and wait: when a trunk becomes available,
Communication Manager will call the extension that placed the original call. The caller will hear
3 short, quick rings. The caller doesn't need to do anything but pick up the handset and wait:
Communication Manager remembers the number the caller dialed and automatically completes
the call.
This field appears when the Direction field is outgoing or two-way.
